历史哲学是当代哲学的灰姑娘,哲学家们从不认为历史哲学家处理的主题关乎任何重大的理论旨趣和紧迫性。在他们眼里,历史哲学关心的问题无非就是哲学家们在别处取得的成果如何能够或者应该怎样运用到历史写作领域中,而且当代历史哲学家在改变其同事所给予的较低评价方面也少有作为。本文将论证丹托在持此种观点的历史哲学家中是一个例外,因为他关于表现的哲学可以帮助我们理解文本是如何与其对象相联系的。(20世纪)语言哲学的主要缺点无疑就是,它从不费心去探究文本的哲学奥秘。历史写作是一座哲学金矿,在这点上我们必须感谢丹托的提醒。  相似文献

Among older youth transitioning from the foster care system, this longitudinal study examined the association of religious and spiritual capital to substance use in the past year at age 19. Participants consisted of African American (N = 179) and White non‐Hispanic (N = 133) older youth in foster care. Drawing from social capital theory, it was posited that religious service attendance (a proxy for religious capital) and belief in a spiritual force (a proxy for spiritual capital) would be inversely associated with substance use. Multiple logistic regression results indicated support for the first and second hypothesis for White foster youth only. Among White foster youth, more frequent religious service attendance and greater belief in a spiritual force were associated with a lower likelihood of illegal substance and polysubstance use. No association between religious or spiritual capital and substance use was found among African American foster youth. The findings underscore the importance of conducting spiritual assessments to help ensure older foster youth who have strong religious or spiritual orientations are in environments where they are accommodated and supported.  相似文献

This paper develops a warning zone approach to make variance investigation decisions for a multiperiod process. The assumed cost generation process varies between an in-control and out-of-control state. These states cannot be directly observed, but must be inferred from the reported cost variances. Using the warning zone method of inference, the manager investigates the process whenever an upper threshold is exceeded or a lower threshold is exceeded for two consecutive periods. A four-state Markov chain models the resulting decision process. Steady state probabilities are derived for this chain and are used to obtain explicit formulas for the effectiveness and efficiency of the decision process. These formulas permit computation of the cost savings attainable by the warning zone method. Compared to other decision rules, the warning zone method is much simpler than the theoretically optimal Bayesian revision method, but uses more information than the Markovian control limit method. Numerical comparison of results shows that the warning zone method usually captures most of the available cost savings, even in cases where the Markovian control limit method does not perform well.  相似文献

In this article we make use of inclusive masculinity theory to explore online media representations of male homosexuality and masculinity within the increasingly popular combat sport of mixed martial arts (MMA). Adopting a case-study approach, we discuss narratives constructed around one aspirational male MMA fighter, Dakota Cochrane, whose history of having participated in gay pornography became a major talking point on a number of MMA discussion/community Web sites during early 2012. While these narratives attempted to discursively rescue Cochrane’s supposedly threatened masculinity, highlighting both his “true” heterosexuality and his prodigious fighting abilities, they also simultaneously celebrated the acceptance of homosexual men within the sport that Cochrane’s case implied. Thus, we suggest that these media representations of homosexuality and masculinity within MMA are indicative of declining cultural homophobia and homohysteria and an inclusive vision of masculinity, as previously described by proponents of inclusive masculinity theory.  相似文献

The empirical literature on the impact of HIV on the quality (Q) and quantity (N) of children provides limited and somewhat mixed evidence. This study introduces individual HIV risk perceptions, as a predictor of mortality, into a Q–N investment model. In this model, higher maternal mortality predicts lower N, while higher child mortality predicts lower Q. Thus, the two effects together make likely negative associations between HIV and both Q and N. Based on longitudinal micro-data on mothers and their children in rural Malawi, our results suggest that higher mothers’ reported HIV risk reduces both child quality, as reflected in children’s schooling and health, and child quantity, when the perceived risk is already moderate or high. The effects are sizable and, in the case of Q (schooling and health), are found for children and teenagers, both boys and girls, while in the case of N, they are found for young and mature women.  相似文献

This article will review and analyze Bosnia’s political, economic and cultural ties with the Middle East, most especially Turkey, Iran, Saudi Arabia and Israel, as well as the evolution of Muslim identity in that republic, especially since the late 1960s when there was an internal liberalization process in part influenced by Yugoslavia’s policy on non-alignment. Today, Bosnians of all ethnic and religious backgrounds must contend with internal divisions and tensions exacerbated by the 1992–1995 war while utilizing a very cumbersome political system that may have brought peace at the expense of unity. Bosnia’s geographical location draws that country toward the rest of Europe while history and the legacy of the Ottoman Empire, also draws Muslims toward the Middle East.  相似文献

Beginning in 2000, in economically advanced countries, a remarkable bifurcation in fertility levels has emerged, with one group in the moderate range of period total fertility rates, about 1.9, and the other at 1.3. The upper branch consists of countries in Northern and Western Europe, Oceania and the United States; the lower branch includes Central, Southern, and Eastern Europe, and East and Southeast Asia. A review of the major theories for low-fertility countries reveals that none of them would have predicted this specific bifurcation. We argue that those countries with fertility levels close to replacement level have institutional arrangements, and related policies, that make it easier, not easy, for women to combine the worker and mother roles. The institutional details are quite different across countries, suggesting that multiple combinations of institutional arrangements and policies can lead to the same country-level fertility outcome. Canada, the only exception to this bifurcation, illustrates the importance of the different institutional structures in Québec compared to the rest of Canada.  相似文献
